Embodiment approach 1

[0073] Implementation Mode 1: Refer to Figure 10 and Figure 11 , the first auxiliary part 14 includes at least two separate auxiliary sub-pieces 141, which are divided into at least two auxiliary sub-pieces 141 of column unit L along the third direction D3, and the column unit L includes at least one auxiliary sub-piece 141, along the third In direction D3, the first parameter of the first auxiliary part 14 decreases gradually;

[0074] The first parameter includes at least one of the following parameters: the area of ​​the auxiliary sub-element 141 on the first plane P1, the thickness of the auxiliary sub-element 141 in the fourth direction D4, the magnetic energy product of the material selected for the auxiliary sub-element 141, and The number of auxiliary sub-items 141 in each column unit L.

[0075] In Embodiment 1, the magnetic first auxiliary component 14 may be a split structure, wherein, along the third direction D3, auxiliary sub-components 141 whose area on the ...

Embodiment approach 2

[0080] Implementation mode two: refer to Figure 12 and Figure 13 , the first auxiliary part 14 has an integral structure, and along the third direction D3, the second parameter of the first auxiliary part 14 decreases gradually;

[0081] The second parameter includes at least one of the following parameters: the width of the first auxiliary member 14 in the first direction D1, and the thickness of the first auxiliary member 14 in the fourth direction D4; the fourth direction D4 is perpendicular to the first direction D1 and a second direction D2.

[0082] In the second embodiment, the magnetic first auxiliary part 14 can be an integrated structure, wherein, along the third direction D3, an integrated structure whose width in the first direction D1 decreases sequentially can be adopted, or can be adopted in the fourth direction D3. An integral structure in which the thickness in the direction D4 decreases sequentially.

[0083] Exemplarily, the first auxiliary element 14 o...

Embodiment approach

[0113] refer to Figure 5 and Figure 6 , the flexible display device 1000 may further include a pulley 400 and a traction belt 500, a cavity is formed when the first housing 100 is slidably connected with the second housing 200, the pulley 400 and the traction belt 500 are arranged in the cavity, and the pulley 400 Set parallel to the reel 13, the traction belt 500 is wound around the pulley 400, and one end of the traction belt 500 is connected with the end of the sliding coil area 32 away from the fixed area 31 (that is, the end of the sliding coil area 32 not connected with the fixed area 31), and the traction The other end of the strap 500 is connected to the second case 200 .

[0114] When the support member 12 and the corresponding groove structure 21 slide along the second direction D2, the distance between the pulley 400 and the reel 13 is constant. That is, when the flexible display panel 300 is rolled up and unfolded, both the pulley 400 and the scroll shaft 13 mo...

Abstract

The invention provides a flexible display device, and relates to the technical field of display. In the flexible display device capable of achieving screen unfolding and rolling, at least part of supporting pieces of a first shell are provided with first auxiliary pieces, the side, close to a rolling shaft, of a sliding rolling area of a flexible display panel is correspondingly provided with a plurality of second auxiliary pieces, and the second auxiliary pieces are arranged on the side, close to the rolling shaft, of the sliding rolling area of the flexible display panel. Magnetic adsorption can be generated between the second auxiliary part and the first auxiliary part. In the rolling and unfolding process of the flexible display panel, a first auxiliary part on a first shell can generate magnetic adsorption with a second auxiliary part, close to the first auxiliary part, on the flexible display panel, so that an arching trend generated by bending of the flexible display panel can be eliminated through the magnetic adsorption effect of the first shell on the flexible display panel. Therefore, the phenomenon that the flexible display panel arches and is uneven during bending is avoided.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a flexible display device. Background technique [0002] Compared with traditional display screens, flexible display screens have significant advantages such as bendability, good flexibility, and light and thin volume, and are currently a type of display screen that has attracted widespread attention in the field. Among them, the scroll screen, as a flexible display that can be rolled up and unfolded according to user needs, provides a new human-computer interaction experience. [0003] The flexible screen of the scrolling screen is stacked with multi-layer structures and has its own rebound force. When it is bent, the flexible screen will release the rebound force and produce uneven arching. Contents of the invention [0004] The present disclosure provides a flexible display device, so as to solve the problem of uneven arching when the existing flexible screen is b...
